Add those accounts to any shares on their respective machines and grant appropriate permissions.

Select the next availabe drive letter (we'll just pick Z for this example) and in the "Folder<" field enter the following: \\PC 1\shared
Now click on "Finish" and your drive should map giving you direct access to that shared folder and it's contents.

How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
